einen ron omis.svi/'Ann Apiilication filari Becember The invention-relates tov molds for Shaping relation to molds having a funnel or guide' lassociated therewith for directing; segregated mold charges delivered freine glass feedlng device into aoclhrate position 1n the der to prevent the glass from adhering to the funnel. If 'the funnel -is formed inte# grelly with the body portion of the niolrh the transfer oheat thereto from the' mold through conduction will, maintain the funnel at :i temperature Substantially that of the mold.

Oneot the objects of the present invention is to prevent excess or harmful limiting oi the funnel by providing .ineens Jfor iuole pendently cooling the funnel and for minimizing the exchange of heat hetween one or both of the body portions of the mold and the funnel.

Other objects of the invention will appear from the 'following description and claims.

In the accompanying drawings l- Figure 1 is e plan view of a divided. mold having a funnel portion formed integrally with each half or section and partially separeted therefrom by a series oi radially extending apertures;

Fig. 2 1s a vertical sectional viewteken lon line 2-2 or" Fig. l; and

Fig. 3 is view partly in side elevation :ind partly in vertical section, illustrating another embodiment of the invention.

Referring to the drawings, a divided mold constructed according to the invention is shown in l and 2 es comprising* two cooperating halves, each composed of :L body portion l, -a 'funnel portion 53,4'i`ormedintegrally therewith, und e noch ring At the 'gum-iure of the 'funnel and body Yportions; e. plurality of vmclially extending apertures l is provided which reduces the amount ot' metal :it thir point and materially reduces l the aroountof heat transferred Jfrom the body of the mold to the funnel through cou-- duction. These apertures; or holes also permit ucccSS oi' ulr between the body und funnelfportions oi the mold, thereby prin/idil, 15925. Serial No. 76.219.

ing insulation which minimizes the transfer 'of heet to the funnel through radiation.

In Fig. 3 there is illuetruted e, further juncture of its bodylyand funnel portious- In thiS embodiment the funnel portion 2 is of shell-like struc-ture to provide :i passage G tor the circulation ot e cooling medium withdrawn through pipes v7 and S. l,

' The groove 5 nmterially reduces theY oi Sectional aroiv'o'li 'the inold et' Athis point :und eifectively reduces the oxohengeof,heartbo tween the body und, funnel-.portions of the mold. That is to eey, the heat of the mold is prevented from' being transmitted readily to the vfunnel and, converseiy,the cooling;r medium circulating about the funnel is Vpre-- vented from materially lowering' the temperature of the body portion of the mold.
